Abstract

The invention discloses a polychrome painting pigment prepared by taking red mudstone as a coloring agent. The polychrome painting pigment is characterized by comprising the following steps: roughly smashing and sieving the red mudstone; performing chemical ball milling by using mechanical force, and mixing with ceramic flux ingredients; adding water, stirring uniformly, coloring and roasting to obtain the product, wherein the roasting temperature is 780-850 DEG C. The polychrome painting pigment with excellent color generation is prepared by taking cheap red mudstone as a major raw material in combination with a mechanical force chemical ball milling method. Compared with a conventional preparation method of the polychrome painting pigment, the preparation method has the advantages of simple and convenient process, no environmental pollution, high yield, low energy consumption, low cost and pure color, thereby achieving a wide market prospect.

Description

Technical field [0001] The invention belongs to the field of inorganic non-metallic materials (ceramics), and specifically relates to a ceramic on-glaze Xi-red pigment prepared by using red layer mudstone as a colorant. Background technique [0002] In the prior art process, the colorant of the Si-red pigment on ceramic glaze is α-Fe 2 O 3 , It is made by calcination of ferrous sulfate at 800~1000℃, and then mixed with a certain amount of flux to prepare the ceramic on-glaze Xi Chi pigment. Among them, flux occupies more than 80%, coloring agent α-Fe 2 O 3 10% is slightly stronger. The baking temperature of the on-glaze Xi Chi is generally between 750 and 850 ℃. [0003] The red bed refers to a set of purple-red, variegated sandstone, mudstone, siltstone and shale deposited in the Jurassic, Cretaceous and Tertiary. It is a clastic sedimentary rock layer dominated by continental deposits, mostly soft The rock and the hard rock are interbedded and produced with weak interlayer bond...
